Tagrisso 80mg drugs Interaction

Tagrisso 80mg tablets concomitant with strong CYP3A4 inducers, leads to reducing the exposure of Osimeritinib, this may causes reducing the effect of Tagrisso 80mg.

Avoid the concurrent use of strong CYP3A4 inducers with Tagrisso 80mg tablets.

Tagrisso 80mg tablet concomitant with BCRP substrates may causes elevating the exposure of BCRP substrates. Thus, results as raising the adverse effects related to BCRP substrates

Avoid concurrent use of Tagrisso 80mg tablets with drug which activate the QT prolongation. In this case patients should be experienced with periodic ECG monitoring.
